LEVELING-MACHINE.

T 0 all 'whom it may concern Be it known that I, VARREN FRAsiER, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Leveling-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to leveling machines, and moreparticularly to that type of machine which comprises a. leveling rolland a cooperating shoe supporting jack relatively movable to change therelative longitudinal position of the roll and jack.

The object of the present invention is to provide la machine of theabove character which is simple in construction and which is capable ofsecuring uniformly good results upon varying classes of shoes.

lVith the above object in view, one feature of the inventioncontemplates the provision* 1n a machine of the class described having aleveling roll provided with one or more striking faces and a shoesupporting jack, of means interposed between the roll and shoe sole toreceive the direct blows of the striking faces as the roll is rotated. y

Still further features of the invention consist in certain novelfeatures of construction,

combinations and arrangements of parts hereinafter described andclaimed, the advantages of which will be obvious to those skilled in theart from the following description. 1

'In the accompanying drawing,la side elevation of a machine embodyingthe several features of the invention in their preferred form isillustrated. v

The machine shown in the illustrated embodiment of the invention isdesigned more particularly for operation upon the soles of turn shoesand it is considered desirable when leveling these shoes to deliver aseries of blows upon the sole of the shoe to beat out the sole and causeit to conform to the curvature of the last. conveniently performed by acontinuously rotated leveling roll provided with a. plu-A rality ofstriking faces which are arranged to deliver a series of rapid blowsupon thesole as the shoe supporting jack is moved Specification ofLetters Patent.

under the roll. In the present invention, the beatingkout operation issatisfactorily per` formed and the sole is bedded upon the last withoutmarring or otherwise injuring the surface by the provision of a flexibleor ref silient shield which engages with the sole and which is arrangedto receive the direct blows of the striking faces as the roll isrotated. In the simplest and most efficient form of the invention whichhas yet been devised, this shield consists of a curved metallic bandwhich surrounds the lower portion of the roll and which is interposedbetween the roll and shoe in such a manner that when the roll is rotatedthe striking faces successively contact with the lowest portion of theband which engages the shoe.

The machine consists principally of a shoe supporting jack 2 pivoted tothe machine frame at l and a leveling roll 5 journaled in the outer freeend of a roll supporting arm 6 which is p'ivoted in the upper portion ofthe machine frame at T. The roll v5 consists of a plurality of smallrolls 8 which are arranged to successively act upon the sole as the rollis revolved and the faces of which constitute the striking faces of theroll A continuous rotation is imparted to the leveling roll in the usualmanner from a main drive shaft 10, a drive pulley 11 mounted thereon,and connecting belts 12 and 13. The roll is pressed downwardly upon theshoe sole by a tension spring 16 which is connected to the frame at itslower end by a link 17 and to the roll carrying arm at its upper end b'yan adjustable connection consisting of a threaded link 18 and'hand wheel19 arranged to adjust the tension of the spring g and vary the pressureof the roll upon the work. 'lh-e downward movement of the roll when theshoe is removed from engagement therewith is limited by a stop rod 2Oconnected at one end to the frame of the machine and at its opposite endthrough an adjustable hand wheel 2l with a rearwardly extending portion9.2 formed upon the arm 6.

The leveling roll 5 is journaled in a head which is swiveled in theouter-end of the roll carrying arm in order that the roll may be tiltedlaterally and cause the sole to conform to the curvature of the last incross section. A simple and efficient mechanism under the control of theoperator ris pro` vided for securing this lateral inclination whichconsists of a toothed segment 26 pivoted at 27 upon the supporting arm 6and meshing with a bevel gear 28 pinned to the inner end of the head 25.The toothed segment 26 is oscillated by a handle 30 extending into aposition conveniently accessible to the operator and by manipulating thehandle in a vertical direction any desired lateral inclination may beimparted to the roll. As the leveling roll 5 is rotated, the directblows of the rolls 8 are -received upon a metallic band or shield 31which is supported slightly eccentric to the roll 5 in order that thesmall rolls 8 shall only contact with the lowest portion of the bandwhich engages the sole. The curved band 31 is preferably formed ofresilient sheet metal which is arranged to yield or give slightly wheneach roll Icontacts therewith to4 thu-s transmit the blows of theleveling roll indirectly to the surface of the sole. causing the sole tobe leveled without mai-ring or injuring the surface of the same. Inorder to vary the force with which these indirect blows are deliveredupon the sole, the position of the band relative to the roll may beadjusted, thereby causing the rolls to strike with a greater or lessdegree of force upon the band as the leveling roll 5 is rotated. Theband 31 has one end pivotally secured at 32 to the head 25 and itsopposite end is adjusted relative to the head by a stop screw 33 bearingagainst the upper end of the band. The end of the band is enlarged andprovided with a rectangular slot which embraces a square stud 34 securedin the head 25, thus affording provision for a vertical movement of thisend of the band relative to the head. It will be notedv that when themachine is in operation.l the lowest portion of the band 31 engages withthe shoe sole and the pressure imparted by the spring 16 causes the bandto be forced upwardly with relation to the roll until its movement islimited by the stop screw 33 which positions the band with relation tothe leveling roll 5 and consequently determines the force or extent ofthe blows which are delivered by thev small rolls 8 upon the band.

It is a desirable requisite in machines of this character that the shoesupporting jack may he readily adjusted to acconnnmlate varying sizesand styles of shoes. that the shoes may be firmly clamped in positionupon the jack. and that when clamped upon the jack they shall always besupported in the same position relative to the leveling roll. The jack 2consists of a supporting bed or frame 35 pivoted to the frame of themachine at l and having the usual heel post 36 and toe post 3T slidinglysupported there on. In order to conveniently adjust the positions of theheel and toe posts to accommodate varying sizes of shoes, they areconnected together by an adjusting rod 38 having its ends threaded inopposite directions and connected with the posts 36 and 3T to cause thesimultaneous movement of the posts toward and from one another as therod 38 is rotated in either direction. heel post 36 is or' the usualconstruction having a last pin -lO pivoted thereto at i1 and providedwith mechanism for actuating the .last pin which comprises a pivoted camplate i2 engaging with the lower end of a sliding pin i3 which contactsat its upper end with the -under side of the last pin 40. 1n order tosecure the same relative position of the shoe and leveling rollindependently of the size of shoe, a heel gage l5 is pivotally securedat i6 to the bed of the jack and has an inturned upper end arranged toproject over the heel of the shoe, serving to both position and clampthe shoe when the machine is in operation. lith this construction, theheel gage is permanently fixed in a vertical positionrelative to thejack and also to the toe post 37 which has no provision for verticaladjustment. The heel post of the ack is adjusted vertically to move theshoe into engagement with the gage 45 by mounting the post upon a slide50 which is moved vertically by an operating cam 51 fulcrumed at 52 uponthe bed 35 .and provided with a handle 53. The operating cam 51 isprovided with a curved operating.; face engaging with the lower end ofthe slide and designed in such a manner that when the heel ofthe shoe isforced against the gage 45 lthe cani will retain it in this positionuntil released by the operator. It will be noted that the adjusting rod38 is journaled in the slide 50 and moves vertically with the sliderelative to the toe post 37. The adjusting rod 38 is threaded into a nutwhich -is slidingly mounted in dove-tailed ways 56 formed upon the sideot the toe post 3T, thus causing the toe post to move toward and fromthe heel post when the rod is rotated, but allowing the rod to be movedvertically relative to the toe post without disturbing the relativepositions of the toe and heel posts.

In the present machine, the actuating mechanism is arranged to impartone complete oscillation of the jack back and forth beneath the roll andthe machine is then automatically stopped with the. roll positionedapj'iroximately above the toe ot the shoe. After the machine has beenstopped` the jack is conveniently disconnected from the actuatingmechanism to allow it to be swung out from beneath the roll andfacilitate the removal ot' a Finished shoe and the application ot' a newone. The jack is oscillated by a rotary path cam (30 secured to a shaft61 and rotated from the main drive shaft through the pulleys G2 and G3and a connecting belt 64. The jack is oscil- The lated from the lcam l60through a connecting rodo which is connected to a slide 66 havingprovision for adjustment to and from the fulcrum of the jack to varythe. extent of oscillationilnparted to the jack by the actuating cam.The slide 66 is supported in dove-tailed ways 67 formed in the bed 35and an operating lever- 68 is connected thereto to adjust the positionofl the slide. The slide is retained in any adjusted position by atoothed quadrant 69 which is engaged by a spring pressed latch 7()supported upon the adjusting lever. The drive shaft is actuated by anysuitable form of clutch mechanism which is controlled by a shipper rod75 connected to a forked clutch lever 76 through a bell crank 77. Theshipper rod 75 is normally moved to engage the clutch by 'a spring 78interposed between a bearing member 79 formed upon the frame of themachine and a collar 8O secured to the shipper rod. rlfhe shipper rod isautomatically moved at a predetermined time to disengage the clutch by alever 81 pivoted centrally to the frame at 8:2 and having its upper andlower ends connected respectively with the cam 60 and engaging with theend of the shipper rod T5. The upper end of the lever 81 is convenientlyconnected to the rod 65, thus forming a support for the end ofthe rodand causing the lever to be oscillated at the proper time toautomatically disengage the clutch by the cam 60. In order to. start themachine, the end of the shipper rod T5 must be removed from engagementwith the lever 81 and to this end a memberS is hinged to the free end ofthe shipper rodand is normally positioned in alinement therewith. Atreadle rod 86 is journaled in the frame of the machine below theshipper rod and is connected therewith by a crank arm 87 and connectinglink 88, thus causing the free end of the member 85 to be swung clear ofthe lever 81 when the treadle 86 is oscillatedf 'ith this construction,it will be noted that the machine may be started by swinging the member85 out of its normal position and after the machine is started, if themember is then moved back to its initial position the machine will beautomatically stopped at the completion of a single cycle, or byallowing the member to remain in its raised position, the machine willoperate for' an indeterminate length of time, completing any desirednumber of c vcles.

In order to allow the jack to be con veniently disconnected from theactuating mechanism, the rod is provided with a lateral stud 89 which isengaged by a hook 90 supported upon the slide 66. An operating lever 91is pivotedto the slide above the hook and is connected therewith in anysuitable manner to disengage the hook from the stud 89 and allow thejack tobe swung clear of the roll when the machine is at rest. In orderto hold the rod 65 in engage' to normally maintain the stud 89 in en-lgagement with the hook 90. l
